Mental Theo was born in 's-Hertogenbosch, The Netherlands in 1965, Theo began DJing family get-togethers at the age of ten, selecting records from his parents' stack of soul 55s.

Mental Theo had followed the musical trends from disco to rare groove on to hip-hop during the late '70s and early '80s, he even worked for a hip hop magazine, but the introduction of house into Holland during the middle part of the decade convinced him that he had found his niche. His reputation bloomed during the gabber house explosion of 1990-1993; Mental Theo played on wicked party's together with dj Rob Janssen from Parkzicht Rotterdam.
